I am also wondering what a good dose would be.
ingest all of it, even with 5% alkaloid content ive eaten more than that, i doubt this vendor is supplying you with even half that potency.
a quick run down on the math...
if its 1% 28g = 280 mg mesc alkaloids = mild/threshold
if its 2% 28g = 560 mg mesc alkaloids = moderate
if its 3% 28g = 840 mg mesc alkaloids = strong
if its 4% 28g = 1120 mg mesc alkaloids = heavy
if its 5% 28g = 1400 mg mesc alkaloids = breakthrough threshold
its is most likely that your powder will be 1.5% +- .5% giving you an expected range of 280-540 mgs
an easy way to eat powder is to add a bit of water and make globs that you can chase, this prevents the powder from adhering to your mouth/throat. eating powder is best after a day of fasting with 0 calories and hydrating all day minus 2 hours through 6 hours into the experience. this prevents nausea, as well as laying on your back for a few hours. i strongly reccommend you do this at sunset and break your fast (breakfast) with some fruit at sunrise
you could always do 2-3 ethanol pulls with 151 rum, evaporate and scrape up for full spectrum resin, however expect to lose 10% of your alkaloids even with 3 solid pulls, you really need 4-5, but thats nearly double the time for such a small dose. each pull should be an hour in a hot bath with a bit of acid (twist of lemon, lime juice, etc)
the resin youll make will be about 3x, leaving you with roughly 8.3 g resin, if you manage to get all the cactus out
28g is not enough (unless its super potent) to give you a breakthrough experience, and as such more complicated methods of alkaloid isolation are overkill.
